• Bowlby proposed that a baby's initial attachment experience forms an internal working model, shaping future relationships. Secure attachments lead to functional relationships, while insecure attachments can result in relationship difficulties, being too uninvolved (insecure-avoidant) or controlling (insecure-resistant). Childhood friendships are influenced by attachment, with securely attached children forming better friendships and insecurely attached children facing challenges. Attachment type correlates with bullying behaviour, with secure children less likely to bully. 
• In adulthood, attachment styles affect romantic relationships and parenting. Research McCarthy illustrates the link between attachment types in infancy and adult relationships. Securely attached adults tend to have healthier friendships and romantic relationships, while insecurely attached individuals may struggle with intimacy or maintaining friendships. 
• Parenting styles often mirror one's own attachment experiences, continuing attachment patterns across generations. Bailey found a strong correlation between a mother's attachment classification with their baby and their own attachment to their mother, highlighting the intergenerational transmission of attachment styles.
